TOBACCO PIPE.

Application filed May 25, 1928, Serial No. 280,474., and in GreatBritain June 25, 1327.

This invention, which may be regarded as a development of that describedin specification 271,273, relates to tobacco pipes of the type in whichthere is interposed in the smoke passage a battle devised to clean, cooland lighten the smoke by causing the deposit of nicotine.

Broadly the invention consists in the provision of a two-part battlecomprising an outer element fitted into the mouthpiece and an innerelement adjustable in the outer element, the outer element havinglateral ports and the inner element having at one end a head devised tobreak up the smoke and at its opposite end termed as a valve.

In practice, the outer element is screwthreaded externally andinternally. The external screw-threads engage ten'iale threads in themouth piece. Preferably a radial flange, constituting a stop is formedon the outer element to limit the distance which the outer elementscrews into the mouth piece, so that the portion of the outer elementfrom the flange to the distal extremity of said out-er element which isnot screw-threaded externally projects from the mouth-piece and ishoused within the pipe-stem when the mouth-piece is fitted to the latterin the usual spigot-joint manner. The lateral ports are :l'ormed in thisprojecting portion of the outer element. The inner element consists ot'a screw pin or red having a conical. head at its distal end, that is theend turthest from the mouth, and a tapered point at the proximal end.This inner element screws into the projecting end of the outer element,When the inner element is screwed home, the conical head projects fromthe extremity of the said. projecting end of the outer (lc-llltllt whilethe tapered end of the inner element finds a seating on the end of theunscrewed portion of the bore of the outer element so that the passagethrough the outer element is closed, the said tapered end acting as avalve.

hen the pipe is in use, the inner element is not screwed home, but isscrewed into the outer element to such a distance that the valve is opento the desired extent, and the draught through the mouth piececontrolled as required.

In order that my said invention may be properly understood I havehereunto appended one sheet of explanatory drawings in which Fig. 1 is avertical section of a pipe fitted with a batlie in accordance with theinvention. Fig. 2 comprises an elevation, a plan view and a transversesection of the outer element. F1 3 an elevation of the inner element andFig. 4: is a plan to a larger scale of the assembled inner and outerelements.

Referring to the drawings The two-part battle referred to consists of anouter element 1 and an inner element 2. The outer element 1 is formedwith external screw threads 2, 8 adapted to screw into the mouth piece4, with lateral ports 5, with a flange 6 constituting a stop, and within ternal screw threads 7.

The inner element consists of a screw pin or red 2 having a conical head8 and a tapered end 9. The inner element 2 is screwed into the end ofthe outer element F 1 with the vertex of the conical. head towards thepipe bowl. When the inner elcment 2 is screwed home, the tapered end 9finds a seating on the bore 01" the outer element 1.

ll lien the pipe is in use, the inner element is not screwed home, sothat the smoke can pass through the ports 5 into the bore of the outerelement. The smoker draws smoke through the pipe stem, through the ports5, through the open valve-controlled port, through thebore of the outerOlQI'IlBIlhZLIld through the mouth piece. The conical head h breaks upthe smoke, thereby assisting in the deposit of the nicotine; the brokeni-imolre is drawn through the ports 5 and the valve-contrailled port,the e1tcnt of opening oi the latter being adjusted to control thedraught.

Having now particularly described and ashaving at one end a head devisedto break up the smoke and at its opposite end formed as a valve.

2. A tobacco pipe in the smoke passage of which is interposed an innerbafi'ie element consisting of a screwed pin having a conical head and atapered end and located in the bore of the pipe stem with the vertex ofthe cone towards the pipe-bowl, and an outer 2 I I I 1,707,033

tubular baide element into which said inner element is screwed, saidouter clement bein; formed with lateral ports, with a radial flangeconstituting a stop, and with external screw threads,

In testimony whereof I have herennto set my hand.
